SUBMITTED BY ARTHUR N1ORC - AMSAT A/C #31468
STS-114 Mission Specialists Soichi Noguchi and Steve Robinson wrapped up
their second spacewalk of the mission at 11:56 a.m. EDT today. They
replaced a Control Moment Gyro (CMG) in the International Space
Stationís Z1 Truss. It is one of four CMGs that provide attitude control
to the Station. Since they finished the replacement ahead of schedule,
they also performed some get-ahead tasks for upcoming spacewalks.
The spacewalkers were assisted by Mission Specialist Andy Thomas, who
coordinated the spacewalk's activities from inside. Pilot Jim Kelly and
Mission Specialist Wendy Lawrence operated the Stationís robot arm. The
spacewalk began at 4:42 a.m., and it was the 60th conducted in support
of ISS assembly and maintenance.
Noguchi and Robinson will venture outside of Space Shuttle Discoveryís
airlock one more time on Wednesday. The major task is the installation
of the External Stowage Platform-2 on to the Station.
Meanwhile, the other Space Shuttle Discovery and Station crewmembers are
transferring cargo.
